Smiths mantle clock project

Sorry I could not get back yesterday. My other love is genealogy my family tree.   If you are sure, you now have it sorted. I was going to suggest taking the chime leavers off and starting from the beginning and describing what each part will do when the chiming starts and how to set it.

Hi Old H    still on going but I think I have worked it out , Going to part dismantle and as you say go through it in bits, I think the problem is the relationship between the two pawls in the locking, will post further information later.  Thanks for all the help every body.

I wouldn’t mind doing that anyway OH if you could help. Now I have a clue as to what’s supposed to be happening it would be good way to help it make complete sense.

If you want to start at the beginning, I suggest you remove all parts from the front. When you have done that, put this piece in, move the wheels around, and tell me, in what position is the wheel at next to the fly? Also on the strike, side after the hammer has lifted where that wheel that has a pin next to the fly is. They both need to be around the 10 number on a clock face as that will be the warning for both chime and strike.

Ok, I have taken everything off. I have put that lever back in, haven’t tightened the screw yet. When the hook has stopped the wheel, the other wheel with the pin is at about 2.00 position. On the strike side, when you say after the hammers have lifted, do you mean at the top of the strike or just as they begin to lift?  Just as they lift, the pin is at 10 position,  just before they drop the pin is at about 12 position.

Chime side. The wheel with pin next to the fly needs to around the 10. This gives it the warning, anything over that and the warning is too short.

The strike side. After the hammer has lifted and just dropped, the wheel with the pin needs to be at about the 10. Just put on the green arrow part and the blue arrow gathering pallet, part with the black arrow. When green arrow part drops into the pallet (blue arrow), the two parts should be in the slot brown lines. Make sure when it is trapped the hammer is not on the rise.

I’m not clear about the pins lying at the 10 position OH

Strike side.  After the hammers have dropped the wheels still spin slightly and stop randomly, the pin doesn’t always stop at 10 position. If I hold the wheels, at the moment the hammers fall the pin does seem to be around the 10 position. Is this how you mean to check it?

Chime side.  The pin is at 2 position when the hooked levers are engaged with the other wheel. How do you get it to be in the 10 position?

I put those parts back on. After the hammers have dropped and the lever comes down and is trapped, the pin on the wheel is stopped at 12 position by the green lever part. No hammers are moving.

OH,  I think this may be easier hope you don't mind.

The chime side, you have the pin on the 2nd wheel in the hook, therefore the lifting pallet must have the pin on the lever in one of the recess, if not loosen the screw behind the lifting pallet turn the pallet till the pin is housed.

Next put the minute hand on and take it round till the lever it is lifting drops , now the chime is set up.

Next, the strike,

Take the pallet lifter off.

Lift the rack (the one that counts the strike) past the lever (the one with the green arrow) and let the lever fall and rest the rack on it.

Next, turn the wheel with the pin on it till it hits the lever stop (if the hammer is half way through a strike just turn it till it has dropped) , now put the lifting pallet on with the lever pin housed in the recess.  

All done,

Some  adjustment may be needed on the chime hook so it is free when at the apex of the lever rise, to do this just loosen the screw on the hook lever and adjust it till it is just clear of the pin.  

Also the chime sequence will need to be set, however that is simple and will help when you get this done.

I think it’s correct. With a bit of luck I’ll find out when I put the movement back in the case. If it runs,  all well and good. If not, well I have learned a bit regardless. That’s worth something. Thanks for your help. I’ll let you all know the outcome.

It’s been running and chiming since Friday. I set the time properly on Saturday and it is still correct. I know it has issues and needs some repairs carried out but, all things considered, it wasn’t even working when I got it. 

Thanks everyone for the help and advice.

It all looks good, however no sound? Just check that when it chimes the 1/4 past the hour the four beats (the hammers fall in this order) are 1,2,3,4,  if they do not, most likely the westminster chime will sound odd. Well done though :woohoo-jumping-smiley-emoticon: this is a hard movement to start on, get yourself a time only and take it apart and bush it even if it does not need it as this will be the most common issue you will find on any type of movement.

I don’t think it was chiming in the order you mentioned JD. I Think it’s ok now, although the half hour does not sound as I had expected it. I have some short clips of the quarter, half, quarter to and hour.

All correct. Congratulations.:Bravo:

    • The only markings on the movement are the words Swiss Made, 15 Jewels and a small 5 under the balance arm. I don't currently have a very accurate caliper but I think it is 34.7mm rather than 36.4 as the Unitas 6497 movement wouldn't fit. Here is a picture of the dial side but I haven't seen any writing on it. I do not believe that the movement has ever been changed since it was made in around the 1930s.  
    • I have a nice little carriage clock in for service, very good shape, except for over 0.30mm sideshake of the barrel arbor in the barrel. Thought I would show how I bush these; it seems they often get overlooked or just skipped as they are a little more fussy than just bushing a plate. I measure everything up, then remove the boss in the barrel, and make a bushing that fits from the inside and is stepped, replacing the boss. This way it's captive, and doesn't require a big interference fit to get seated and stay. I turn up the bushing with a boring tool in the lathe, doing the outside as well (running in reverse of course), then do the barrel opening with the same tool. It's a pretty quick process once you have the moves down!    
    • Well the movement is Unitas, but they did make many many different calibers. What is the exact diameter of the movement, and can you get a pic of the dial side? Are there no markings near the balance cock or on the dial side? If not it will take some digging but you will probably find it on Ranfft's site.
    • I must admit I have never even clapped eyes on one like that, but my gut feeling is that you back off the key in the opposite direction to winding, and it will unscrew, then undo the knurled bolt, and pull on it, and *something* should slide out of something else. The chances that I am completely wrong however are around 50% EDIT: Wow.. Barographs are expensive when new.. https://www.metcheck.co.uk/collections/barographs . I'll need to keep an eye out for one, they look pretty interesting, similar to  clockwork seismograph recorders .   
    • Thank you but I should have mentioned before, tried a Unitas 6497 clone movement to see if it was the correct size. The gears are far finer and the escape wheel teeth are the wrong size and it was slightly too short. It has a Swiss Lever escapement as far as I can tell and is about 4.5mm in height. If it helps the mainspring barrel is the size of the winding gear on the top and seems to be fully attached to it.
